Claims

[Scope of utility model registration request]

A heat exchange section has a multilayer structure by alternately stacking corrugated fins and flat separators, and each layer has a large number of parallel channels, and a a pair of side plates that are provided in close contact with each other and serve as outer walls on both sides of the heat exchange section; and a pair of side plates that are provided at both ends of the flow path of the heat exchange section for flowing a predetermined fluid into each flow path of the heat exchange section. A plate-fin heat exchanger comprising a piping connection section, and alternately flowing a low temperature fluid and a high temperature fluid through each layer of the heat exchange section to exchange heat between these two fluids,
The pipe connection portion includes a cylinder that passes through the pair of side plates in the thickness direction thereof and has both ends projecting outward from the side plates, a blind plate that closes one end of the cylinder, and a flange on the other end of the cylinder. A flange for piping connection provided in a shape,
A plate-fin heat exchanger comprising a communication hole formed in a circumferential wall of a cylindrical body for communicating a flow path of the heat exchange section with the inside of the cylindrical body.
